An integral CRK, sweet idea !
I doubt he'll ever make one but if he did I'd buy it. I don't think that they're necessarily better than the two slab bed design but they are a marvel in their own right that is a pleasure for any knife but or machinist to own and spend time using or just plain looking at. I've had a couple of Estrella's, fondled several more, handled the Microtech Anax ( best non otf knife they ever made), and I had the pleasure of spending some time with a Rassenti Nirvana( awesome ). I liked them all very much but 2 things always bugged me.
1) they're heavy when compared to a non integral.
2) I wondered how they'd repair them if the lock ever wore out.
On the Estrella it'd be a new blade, not sure if the stop pin could've been pressed out of the Nirvana and a larger hole drilled through it to accommodate a larger pin to reduce lock engagement could be done or not.
I know that neither of these two things are an issue on a Sebenza.
The feel of the full backed titanium integral handle is superlative though and I really would like to see Chris flex his muscles and show the custom guys( and even Microtech with the Anax ) how it's done !
